What matters now
- The price sits above even our optimistic bull case ($5.51). The favourable scenario is already priced in.
- The large gap to fair value rests on thin data (low evidence): fewer applicable models and a shorter history. Read it with extra caution.
- Solid but not exceptional quality (50/100) and above fair value, neither a clear bargain nor a standout compounder.
- A fairly wide model range ($2.23 to $5.51) leaves room in how you read the outcome.

Analysis
Fastly, Inc. Class A Common Stock (FSLY) currently trades at $21.12, while our model-based Fair Value estimate is $3.87, implying the stock looks roughly 445.9% overvalued today. The Quality Score stands at 50/100 (solid quality), in the Technology sector. Bull case: the DCF Models group reads highest at a median of $8.29 per share, and 0 of the 7 models we run sit above the $21.12 price. Bear case: the Asset-Based group reads lowest at $3.98, and 7 of the 7 models stay below the price. Evidence for this calculation is low.
Over the trailing twelve months, Fastly, Inc. Class A Common Stock generated revenue of $653M at a net margin of −15.8%. Revenue grew 19.8% year over year. It earns a return on equity of −10.7%. Net debt stands at $250M. Fundamentals as of Sep 1, 2026
Our scenario range runs from $2.23 (bear case) to $5.51 (bull case); at $21.12, the current price sits above that range. Bear and bull are the same models run on conservative and optimistic assumptions (margins, growth, valuation multiples), so a plausible valuation range, not a price target. The share trades about 39% below its 52-week high and 236% above its 52-week low, currently above its 200-day average. For context, the median of 10 Technology peers we cover trades at −38% fair-value upside, at −82%, FSLY screens richer than that median.
Fair Value models
Each model estimates fair value its own way; the Fair Value above is the evidence-weighted, family-balanced blend. Evidence (0–100) measures how completely this model’s inputs are available: well-fed models carry more weight in the blend. The spread across models is intentional, each one stresses a different value driver; dividend models, for instance, come out structurally low when payout is small. Every input is real reported data, nothing guessed.
All 7 models by family
Widest divergence: DCF Models ($8.29) versus Asset-Based ($3.98). Highest evidence: FCF DCF (74).

Quality Score breakdown
Of which business quality 53 · Market factors (momentum, volatility) 64
Non-valuation factor families (profitability, growth, cashflow, financial strength, momentum …), each academically grounded. Valuation itself sits in the Fair Value and is deliberately excluded here to avoid double-counting.
All values are scores from 0 to 100 (100 = best against fixed, research-based bands), not percentages. The three market factors (momentum, 52-week proximity, low volatility) are displayed but carry zero weight in the headline number: market sentiment is not a business property.
